LED Drivers – RACT25-700 Application Field and Working Principle
LED drivers are special forms of power supplies that are designed to power light-emitting diodes (LEDs). The RACT25-700 by Resonant AC Technology is a constant current LED driver with a rated output of 700mA. It is suitable for indoor LED lighting applications such as downlighting, panel and recessed lighting.
Design Features
The RACT25-700 features a 4:1 constant current range of 100mA to 700mA, adjustable from the bottom or top of the device. It is designed with high efficiency, low power usage, and a wide input voltage range of 120-277Vac. It also offers overload and short circuit protection. Additionally, the scalable design allows it to be used with a wide variety of LED luminaires.
Working Principle
An internal oscillator provides a substantial current source that feeds a resonant circuit. The current is then shifted through the use of an active phase control circuit. This is done by modulating the gate current of a power field-effect transistor (FET), which is then phase-shifted to provide the output. The magnitude of phase shift provides control over the output current.
The AC waveforms of the outputs are rectified and filtered using a rectifier-diode bridge and capacitors, producing a DC voltage. The output is then regulated by the rectified peak current, which is regulated by the output voltage. Thanks to the process, even load without transformer can be supplied with stable DC voltage.
Applications
The RACT25-700 can be used for a variety of indoor LED lighting applications, including but not limited to panel lighting, recessed lighting, retail and residential lighting, and downlighting. As the device is designed for high efficiency and low power usage, it is perfect for installations where energy saving is a priority.
Conclusion
The RACT25-700 from Resonant AC Technology is a constant current LED driver designed for a variety of indoor LED lighting applications. As the device features a wide range of adjustable current, adjustable from either the bottom or the top of the device, it is ideal for lighting installations where high efficiency and low power usage is a priority.
